[0044] The present invention provides a steel bar bending machine. Figure 1-Figure 7As shown, it includes a frame 200 and a lifting component 1, a bending plate 2 and a panel protective cover 3 arranged on the frame 200. The lifting component 1 is arranged on the frame 200. The lifting component 1 includes a lifting bracket 11. The lifting bracket 11 is provided with a central shaft 4. The axial direction of the central shaft 4 and the lifting direction of the lifting bracket 11 are both arranged in the vertical direction. The lifting bracket 11 can drive the central shaft 4 to perform lifting and lowering movements; the bending plate 2 is rotatably connected to the lifting bracket 11, the bending plate 2 is coaxially arranged with the central shaft 4, and a bending shaft 5 is installed on the bending plate 2, which can drive the bending shaft 5 to rotate around the central shaft 4; the panel protective cover 3 is arranged on the frame 200 and above the bending plate 2. When the lifting bracket 11 drives the central shaft 4 and the bending shaft 5 to rise and fall, the central shaft 4 and the bending shaft 5 can reciprocate through the upper and lower sides of the panel protective cover 3.

[0045] The steel bar bending machine provided by the utility model is provided with a fixed central shaft 4 and a rotatable bending shaft 5 on the lifting bracket 11, so that the lifting bracket 11 can drive the central shaft 4 and the bending shaft 5 to move up and down synchronously, and the panel protective cover 3 is provided. Figure 3 , when the central axis 4 and the bending axis 5 rise synchronously to a position higher than the upper surface of the panel protective cover 3, the steel bar 100 bending operation can be performed; Figure 2 When the center axis 4 and the bending axis 5 are synchronously lowered to a position lower than the upper surface of the panel protective cover 3, the finished steel bar 100 after bending will remain on the panel protective cover 3, and the finished steel bar 100 will be unloaded from the panel protective cover 3 smoothly, which is convenient and quick, and the bent steel bar 100 can be loaded, which is easy to operate, can greatly reduce the intensity of manual labor, and improve the bending efficiency of the steel bar 100. It can be understood that in order to cooperate with the movement of the center axis 4 and the bending axis 5, the circumferential edge of the panel protective cover is fixed to the frame 200, and the panel protective cover is provided with a center hole corresponding to the center axis 4 and an annular groove corresponding to the bending axis 5. When the center axis 4 and the bending axis 5 move up and down, the center hole and the annular groove are respectively penetrated. When the bending axis 5 moves in a circle to bend the steel bar 100, the bending axis 5 can move in the annular groove, ensuring the movement trajectory of the bending axis 5 and improving the bending quality of the steel bar 100. By setting the annular groove, the bending angle can be limited to avoid excessive bending.

[0046] In some embodiments, the lifting assembly 1 also includes a base 12, a lifting drive member 13 and a mounting pillar 14. The base 12 is fixed to the frame 200. A guide shaft 121 is provided on the base 12, and the lifting bracket 11 is slidably installed on the guide shaft 121; the lifting drive member 13 is fixed on the base 12, and the output end of the lifting drive member 13 is connected to the lifting bracket 11 to drive the lifting movement of the lifting bracket 11; the mounting pillar 14 is provided on the lifting bracket 11, and the top end of the mounting pillar 14 is fixedly connected to the center shaft 4, and the circumferential rotation of the mounting pillar 14 is installed on the curved disk 2.

[0047] Combine Figure 2 and Figure 3 As shown, the lifting drive 13 can be a linear drive mechanism such as a cylinder. The output end of the lifting drive 13 is arranged in the vertical direction to drive the lifting movement of the lifting bracket 11, thereby achieving the lifting movement of the central axis 4 and the bending axis 5. By providing a guide shaft 121, the lifting movement of the lifting bracket 11 can be vertically guided, ensuring the smooth lifting movement of the central axis 4 and the bending axis 5.

[0048] In some embodiments, the lifting assembly 1 also includes a central fixing seat 15, which is arranged at the top of the mounting pillar 14. The central fixing seat 15 is provided with a mounting hole 151, and the central axis 4 is inserted into the mounting hole 151 for fixation. The circumferential rotation of the central fixing seat 15 installs the bending disk 2.

[0049] like Figure 2-Figure 4 As shown, the center fixing seat 15 is fixedly connected to the mounting pillar 14 by multiple bolts. The mounting hole 151 of the center fixing seat 15 is a stepped hole, and the plug-in end of the center shaft 4 is a stepped shaft. During installation, the plug-in end of the center shaft 4 is inserted into the mounting hole 151, and the stepped shaft and the stepped hole match and realize plug-in positioning, which is convenient for disassembly.

[0050] In some embodiments, a spring pin 41 is provided on the side wall of the plug-in end of the central shaft 4 , and the spring pin 41 can abut against the inner wall of the mounting hole 151 .

[0051] like Figure 5 As shown, the spring pin 41 is provided at the plug-in end along the radial direction of the central shaft 4. When the plug-in end of the central shaft 4 is inserted into the mounting hole 151 of the central fixing seat 15, the elastic end of the spring pin 41 abuts against the inner wall of the mounting hole 151, thereby fixing the central shaft 4 and facilitating the replacement of the central shaft 4. The bending shaft 5 is plugged and installed on the bending disk 2 and is screwed or clamped on the bending disk 2. In some embodiments, the cross-section of the bending shaft 5 is circular, and the cross-section of the central shaft 4 is oblong, rectangular, or arc-shaped. While the central shaft 4 clamps and positions the steel bar 100, it can have a certain contact line in the long axis direction of the steel bar 100 to ensure the bending position of the steel bar 100, thereby improving the bending quality of the steel bar 100.

[0052] In some embodiments, a sliding sealing assembly is provided between the central fixing seat 15 and the curved large plate 2 .

[0053] like Figure 2-Figure 4As shown, the center shaft 4 is inserted and fixed on the center fixing seat 15. The outer side of the center shaft 4 is covered with a top cover 22, which is fixedly connected to the bending plate 2. The top cover 22 can be pressed against a step surface of the center shaft 4 to achieve an upper limit on the top cover 22. A sealing ring 21 is provided between the top cover 22 and the outer peripheral wall of the center fixing seat 15. When the bending plate 2 drives the top cover 22 to rotate, the sealing ring 21 slides and seals between the center shaft 4 and the top cover 22, which can prevent dust from entering between the center shaft 4 and the top cover 22 during the bending process of the steel bar 100, thereby playing a sealing and protective role. Furthermore, to facilitate installation, the central through hole on the bending plate 2 has a larger aperture. A sealing ring 21 is also provided at the central through hole of the bending plate 2 below the top cover 22. The sealing ring 21 is used to seal the gap between the bending plate 2 and the center fixing seat 15, and at the same time helps to improve the coaxiality of the bending plate 2 and the center fixing seat 15.

[0054] In some embodiments, the lifting assembly 1 also includes a rotating drive member 16, a transmission assembly 17 and a transition seat 18. The rotating drive member 16 is arranged on the lifting bracket 11; the transmission assembly 17 is arranged at the output end of the rotating drive member 16, the transition seat 18 is sleeved with the central fixed seat 15 and is coaxially arranged with the central axis 4, the transition seat 18 is fixedly connected to the transmission assembly 17, and the curved plate 2 is fixedly connected to the transition seat 18.

[0055] Combine Figure 2-Figure 4 As shown, in this embodiment, the transmission assembly 17 includes a small gear 171 and a large gear 172, wherein the small gear 171 is arranged at the output end of the rotating drive member 16, and the rotating drive member 16 is configured to drive the small gear 171 to rotate; the large gear 172 is mounted on the mounting column and is rotatably connected to the mounting column, and the large gear 172 is transmission-connected to the small gear 171; the transition seat 18 is coaxially arranged with the central axis 4, and the transition seat 18 is mounted on the central fixed seat 15, and the bottom end of the transition seat 18 is fixedly connected to the wheel disc of the large gear 172 and can rotate synchronously with the large gear 172, and the curved large disc 2 is fixedly connected to the top of the transition seat 18. The rotating drive member 16 includes a servo motor 161 and a reducer 162. The servo motor 161 is fixed to the reducer 162, and the reducer 162 is fixed to the lifting bracket 11. The small gear 171 is installed on the output shaft of the reducer 162. When the servo motor 161 is working, it drives the small gear 171 on the reducer 162 to rotate. The small gear 171 is meshed with the large gear 172 for transmission, thereby driving the bending plate 2 to rotate, realizing the rotation movement of the transition seat 18 and the bending shaft 5 on the bending plate 2, and realizing the bending of the steel bar 100. It should be noted that the servo motor 161 drives the bending shaft 5 to rotate around the central axis 4. The forward and reverse rotation of the servo motor 161 can realize the upward and downward bending of the steel bar 100. Figure 6 and Figure 7As shown, the requirement for flexible bending of the steel bars 100 is met. Furthermore, the spacing between the two central shafts 4 is slightly larger than the outer diameter of the steel bars 100. Based on the height of the top ends of the central shafts 4 and the bending shafts 5 protruding from the panel protection cover, multiple steel bars 100 can be positioned within the two central shafts 4, thereby achieving a synchronous bending process for multiple steel bars 100.

[0056] In some embodiments, a first bearing 6 is provided between the transition seat 18 and the central fixing seat 15 to improve the coaxiality of the transition seat 18 around the central fixing seat 15. Similarly, when the large gear 172 is sleeved on the mounting post 14, the two are connected by a second bearing 7 to improve the coaxiality between the large gear 172 and the mounting post 14 and reduce rotational friction.

[0057] In some embodiments, a connection joint 131 is provided at the output end of the lifting drive member 13 . A floating pressure cover 132 is provided on the connection joint 131 . The floating pressure cover 132 is fixedly connected to the lifting bracket 11 .

[0060] Combine Figure 1In this embodiment, four guide sleeves 111 are symmetrically arranged around the circumference of the lifting bracket 11. The four guide sleeves 111 are fixedly connected to the lifting bracket 11, such as by welding or forming an integral structure. A guide shaft 121 is sleeved on the guide sleeves 111. When the lifting drive 13 drives the lifting bracket 11 to move up and down, the lifting bracket 11 slides along the guide shaft 121, ensuring the directional stability of the lifting bracket 11 and improving installation accuracy. To reduce friction between the guide sleeves 111 and the guide shaft 121 and improve guidance, a sleeve 122, such as a copper sleeve, is further provided between the guide sleeves 111 and the guide shaft 121. The copper sleeve is mounted on the guide shaft 121 and sandwiched between the guide sleeves 111 and the guide shaft 121, thereby improving the directional stability of the guide sleeve 111 and reducing sliding friction during movement.

[0061] In some embodiments, a buffer pad 112 is provided at the bottom end of the guide sleeve 111 .

[0062] like Figure 2 and Figure 3 As shown, when the lifting bracket 11 descends, the bottom end of the guide sleeve 111 abuts the bottom end of the guide shaft 121. By providing a buffer pad 112, vibration and friction between the guide sleeve 111 and the guide shaft 121 can be reduced, thereby protecting the equipment. It is understood that the buffer pad 112 can be provided at the bottom end of the guide sleeve 111 or on the stepped surface of the guide shaft 121.
